Sorry if this has already been answered. Using a fresh install of Madsonic 5.1.5260 (Win 7 64), I noticed that madsonic-agent.exe throws an exception unless I allow it to connect to 104.25.232.8 - a Cloudflare IP. What is the reason for this?

I've searched long and hard through the forums for an answer, but can't seem to find one. I am very new to this software, so do forgive me if this is a very basic question.
